STALL-DRAIN.

SPECIFICATION forming part of Letters Patent No. 505,232, datedSeptember 19, 1893 Application filed March 20, 1893. Serial No. 466,898.(No model.)

To all whom it may concern.-

Be itknown that I, HENRY SOHIFFER, a citizen of the United States, and aresident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Stall-Drains, of which thefollowing is a specification.

The object of the invention is to provide a new and improved stall drainadapted to be readily and easily fitted in the bottom of the stall andarranged to insure perfect drainage.

The invention consists principally of a series of slats secured at theunder side to cross bars and forming a series of channels or guttersextending a suitable distance in depth between adjacent slats.

The invention also consists of parts and details and combinations ofthesame as hereinafter more fully described and pointed out in theclaims.

Reference being had to the accompanying drawings forming part of thisspecification and in which similar letters of reference indicatecorresponding parts, Figure 1 is a plan View of the improvement asapplied. Fig. 2 is a longitudinal sectional elevation of the same on thelines 2. 2. of Fig. 1. Fig. 3 is an enlarged cross section of the sameon the lines 3. 3. of Fig. 2, and Fig.4 is a longitudinal sectionalelevation of a modified form of the same.

The stall is provided with the usual front wall A, the sides B, and aninclined bottom composed of the front cross board 0, and the drain D,the lower end of which discharges into the gutter I.

The drain D is composed of a series of slats D placed firmly alongsideone of the other so as to form on the under side an unbroken surface aswill be readily understood by reference to Fig. 3. The several slats Dare united on the under side by transversely extending metallic flatbars or battens F let into 7 recesses cut in the slats so that the underside of the bars is flush with the under side of the thereof with arabbet D extending longitudinally throughout the length of the slats andhaving a depth approximately one half of the thickness of the slats.Each rabloet is slightly overlapped by an undercut D of the nextadjacent slat so that a channel D is formed between each two adjacentslats as plainly shown in the enlarged detail Fig. 3. The upper ends ofthe slats are formed with transverse tongues D fitting into acorrespondingly shaped groove 0 of the lowermost cross board 0 so as toconnect the drain D firmly with the crossboards O, see'Fig. 2.

The entire bottom 0. D. rests on a cement floor H in which is formed thetransverse gutter I of suitable depth and inclination to run off theliquid matter, flowing down the channels D which latter discharge attheir lowermost ends into the said gutter I, as shown in Figs. 2 and 4.The gutter I is closed on top by a perforated metallic cover J,extending from the middle of one side B to that of the other side B, sothat each stall has its own cover for that part of the gutter Iextending on the lower or outer end of the stall. The aisle K extendingbeyond the gutter I is curved, or inclined upwardly from the gutter I,and is .a continuation of the cement floor H.

In order to securely hold the bottom 0. D. in place on the fioor H, Iprovide small angle irons L secured with their vertical flanges byscrews or other means to the sidesB; the horizontal flanges resting ontop of the outermost or side slats D and the ends of the cross boards Cas plainly shown in Figs. 1, 2 and 3.

As shown in Fig. 2, the cover J. is flush with the top of the lower endsof the slats D the inner edge of the cover resting in a seat formedtransversely in the slats D while the outer edge of the cover rests in aseat or rabbet formed in the cement floor; The cover is somewhat less inthickness than the depth of the channels D so that they dischargedirectly into the gutter I as will be readily understood by reference tothe said Fig. 2.

As illustrated in Fig. 4 the under side of the wooden cover J is flushwith the under side of the bottom slats D and in this case the inneredge of the cover is cut out to form a transverse rabbet J into whichlead the downwardly beveled ends of the bottoms of the channels formedby the slats.

The aisle is formed with diagonal grooves so that any liquid matterthereon can drain to the cover J and through the perforations in latterinto the gutter I.

It will be seen that the entire construction of the stall drain is verysimple, ample provision is made for perfect drainage and no screws ornails liable to injure the animal project on the upper surface of thestall bottom.

Having thus described my invention, what I desire to secure by LettersPatent is 1. A stall drain comprising a bottom made of cross boards andlongitudinal slats connected at their upper ends with the lowermost ofthe said cross boards and forming top channels between adjacent slats,battens connecting the said slats with each other at the under side andangle irons adapted to be fastened to the sides of the stall and adaptedto engage with their horizontal flanges the top surface of the saidbottom at the sides thereof to securely hold the said bottom to thefloor substantially as shown and described.

2. A stall drain provided with a bottom comprisinga series of crossboards and a drain composed of a series of longitudinal slats inalignment with the said cross boards, each slat being formed on top andon one edge thereof with a rabbet extending throughout the length of theslat, and partly overlapped by an undercut on the next adjacent slat soas to form a longitudinal channel between each two adjacent slats and onthe top thereof substantially as shown and described.

3. A stall drain comprising a bottom made of cross boards andlongitudinal slats forming channels between adjacent slats, the upperends of' the slats being connected by ing with their horizontal flangeson the end slats and the sides of cross boards substantially as shownand described.

4. A stall drain comprising a cement floor formed with a transversegutter, a cover for the said gutter and a bottom extending from thegutter to the head of the stall, the said bottom being inclined and madeof cross boards and longitudinal slats each formed on one side with arabbet overlapped by an undercut on the next adjacent slat for forminglongitudinal channels in the top of the slats and between each twoadjacent slats and battens secured to the under side of the slatssubstantially as shown and described.

5. Astall drain provided with adrain made of slats placed firmlyalongside one of the other, each slat being formed on top and on oneedge thereof with a rabbet extending throughout the length of the slatand partly overlapped by an undercut on the next adjacent slat so as toform a longitudinal channel between each two adjacent slats and on thetop thereof substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 17th day of March, 1893.
